[webkit-dev] Why is ResourceHandle.cpp in WebKit/chromium/src

In investigating the loader, I noticed that Chromium's ResourceHandle.cpp is in WebKit/chromium/src. ResourceHandle is a WebCore/platform abstract. Most of the other implementations of ResourceHandle are in WebCore/platform/mumble/ResourceHandleMumble.cpp. Is there a reason why Chromium uses a different design? Normally, we need a use a virtual function to jump from WebCore to WebKit/chromium. It looks like we're avoiding that in this case, at the cost of blurring the layer boundaries. Adam
